All you need to know about plant growth chambers

If a plant growth chamber with humidity control is required, constant climate chambers from the KBF and KBF PRO series are available as basic units. When operated with a BINDER LED plant light module, the units regulate a temperature range from 10°C to 50°C and a relative humidity from 10% to 50% (KBF series) or 10% to 90% (KBF PRO) series.

In the process of photosynthesis in plants, CO₂ from the air is converted into sugar with water and light energy. In a gas-tight climate chamber, the CO₂ concentration can fall as a result, compromising plant growth. The BINDER LED plant light module is equipped with a pump that pumps the ambient air into the climate chamber at an adjustable flow rate. This ensures that the CO₂ concentration of the earth’s atmosphere (0.04 vol. %) is maintained in the chamber. If an increased CO₂ concentration is needed, a BINDER CO₂ gassing module can be added to the plant growth chamber in order to precisely regulate the CO₂ concentration in the range of 0.05 to 1.0 vol. % CO₂.

With the BINDER LED plant light module, lighting scenarios that approximate natural sunlight can be generated in the climate chamber. Maximum brightness close to sunlight strength is achieved if all 16 LED strip lights are mounted next to each other. 

The light module has three LED color channels that can be adjusted independently of each other: cold white, warm white, and dark red. The white color channels are similar to sunlight in their spectrum. The ratio of cold white and warm white light can be used, for example, to simulate autumnal light conditions that lead to accelerated seed formation. With the dark red channel, the plant’s phytochrome system is triggered.

The light module consists of a light control unit and 16 LED strip lights. 

The light control unit is mounted on the left-hand side of the climate chamber using supplied fastening elements that can be attached to prepared fastening points on the chamber.

The LED strip lights are easy to clip in under the standard chamber racks using integrated metal clips. No tools are required. The strip lights can be repositioned for flexible placement, allowing the configuration to be altered at any time. 

Power supply cables and fresh air lines are routed inside via the chamber’s large oval standard access port. Precisely fitting silicone foam plugs seal the access port.
